The official SizeGenetics website loves talking about this on their own website, but who can blame them? Most penis extenders typically come with either one of two designs; the silicon noose or the plastic strap.

There's nothing inherently wrong with either, but sadly if you buy a device with a strap method that you find uncomfortable tough luck!

By buying the SizeGenetics device, you will get a 16 Way Comfort System, which consists of multiple strapping methods. Chances are one of these methods will be comfortable for you.

Even though SizeGenetics retails for $199, this is a one-time purchase and the manufacturers guarantee that you will see a size gain of up to a few inches in just a few months. The package also comes with spare parts, just in case.
